Question

我想知道如何在同一视图中编辑两个表。我有两个与彼此相关的模型。

在我看来，我正在尝试使用已插入的值重新填充表单选择以便更改它。

模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Products extends Model
{
protected $table = 'products';

public $primaryKey = 'id';

public $timestamps = true; 

public function user()
{
    return $this->belongsTo('App\User');
}

public function material()
{
    return $this->belongsTo('App\Material');
}

}

<?php


namespace App;

use Illuminate\Database\Eloquent\Model;

class Material extends Model
{
protected $table = 'material';

public $primaryKey = 'id';

public $timestamps = true; 

function products(){
    return $this->hasMany('App\Products');
}

}

控制器

public function edit($id)
{
    $product = Products::find($id);

    return view('products.edit')->with('product', $product);
}

查看（products.edit）

@extends('layouts.app')

@include('inc.messages')
@section('content')
<div class="container">
    <h1>Edit</h1>

    {!! Form::open(['action' => ['ProductsController@update', $product->id], 'method' => 'POST']) !!}
        <div class="form-group">
            {{Form::label('title', 'Title')}}
            {{Form::text('title', $product->title, ['class' => 'form-control', 'placeholder' => 'Title'])}}
        </div>
        <div class="form-group">
            {{Form::label('body', 'Body')}}
            {{Form::textarea('body', $product->body, ['class' => 'form-control', 'placeholder' => 'Body text'])}}
        </div>
        <div class="form-group">
            {!! Form::label('material', 'Material') !!}
            {!! Form::select('material',dd($Materials), ['class' => 'form-control']) !!}
        </div>



        {{Form::hidden('_method','PUT')}}
        {{Form::submit('Submit',['class' => 'btn btn-primary'] )}}
    {!! Form::close() !!}
</div>

@endsection

错误输出 为foreach（）提供的参数无效（查看：C：\ xampp \ htdocs \ material \ resources \ views \ products \ edit.blade.php）
